What happens
Batman and Robin investigate a country farm near Metropolis, where they believe Superman is held captive by the dishonest politician George Latimer and the former concentration camp official Dr. Marsh. Their search leads to a confrontation with Latimer's armed henchmen. Inside the farmhouse, they find Superman weakened by a solution of kryptonite and dazed, having lost his memory. The episode is from The Adventures of Superman, a radio serial, and its original air date is June 26, 1947. The transcript covers only the opening part of the story, which ends with the heroes trapped in a cellar as gunmen close in.

Written from the episode itself; it never gives away the ending. Every recording is remastered for the stream: cleaned of rumble, hiss and mains hum (and the old TV whine where we found it), then levelled in two passes to steady broadcast loudness, so one show is never quieter than the next.
